The independent needle valve is designed to be mounted on the side of the aquarium enabling easy access for fine flow adjustment or complete shut off. The CO2 Cylinder / Regulator can be located out of site, behind or under the aquarium.

The Red Sea Co2 Reactor 500 efficiently dissolves CO2 into aquarium water. This fully adjustable, power driven, super compact CO2 reactor will simply and efficiently maintain the desired level of CO2 in a wide range of planted aquariums. The turbulent flow CO2 / water interface inside the reactor ensures almost complete dissolving of available CO2 while non-dissolvable gases are gently vented to the water surface.

Solenoid for automating dosing of CO2. Too much CO2 can reduce the pH in an aquarium to levels that are stressful for fish. For the safe use of CO2 it is highly recommended to automate the CO2 system with either a simple time switch or by a pH controller. The in-line solenoid Control Valve connects the CO2 system with either of these devices.

The high precision fine-flow valve is designed to be mounted on the side of the aquarium enabling easy access for regular flow adjustment or complete shut off. Easily upgradeable for automatic control with an in-line solenoid control valve.

Red Sea is pleased to introduce an exciting new CO2 system for aquariums. The Pro System is a complete, efficient and user-friendly system to maintain a desired level of CO2 in aquariums from 10 to 125 gallons (40 to 500 Liters).
